Feat/custom template per field

[lucasmcht]

Fixes #3695 (Rework of PR #3881)

Reasons for making this change

Currently, to per-field customize the template, it is necessary to send the function/class of the component in the uiSchema, breaking the JSON nature of the uiSchema. It's not possible to provide just the registration key.

This pull request includes updates to the @rjsf/utils package to allow for per-field customization using string keys from the Registry, as well as updates to the documentation to reflect these changes. Additionally, it simplifies the types in the codebase by introducing a new RJSFBaseProps type.

Feature Enhancements

• packages/utils/src/getTemplate.ts: Updated getTemplate() to allow per-field customization using string keys from the Registry.

Documentation Updates

• packages/docs/docs/advanced-customization/custom-templates.md: Updated to include examples of specifying templates using both components and string values from the Registry.

Type Simplification

• packages/utils/src/types.ts: Introduced RJSFBaseProps to simplify and consolidate the properties passed to various template components. This change affects multiple type definitions, including ErrorListProps, FieldErrorProps, FieldHelpProps, FieldTemplateProps, and others.

I'm not sure what kind of documentation I should add, could you specify please ?

[heath-freenome]

I suggest mentioning the ability to add per-field customizations and maybe add an example of a custom template since it is now supported?

Wow, I'm super glad this feature is finally getting into the master branch. It's almost having an one year birthday 🎂. We use this feature extensively to customize the layout of the form. I think its a very nice use case to describe in the docs, since I'm aware it's a very long desired flexibility. I could also contribute by providing the Layout template.

@lucasmcht Also, can you fix the type errors in the themes?
